Introduction: Accurate duct sizing is essential for maintaining efficient airflow in HVAC systems, ensuring optimal performance and energy efficiency. The Duct Size Calculator CFM, designed for airflow and velocity considerations, provides tailored recommendations to assist HVAC professionals and enthusiasts in selecting the ideal duct size. By factoring in the required airflow in cubic feet per minute (CFM) and desired velocity, this tool aids users in achieving effective ventilation and climate control.
Formula: The calculator employs the airflow in CFM and velocity parameters to calculate the recommended duct size. This calculation involves dividing the airflow by the velocity, resulting in a duct size that maintains the desired airflow velocity for efficient ventilation.
How to Use:
- Enter the required airflow in cubic feet per minute (CFM).
- Enter the desired velocity in feet per minute.
- Click the “Calculate” button to obtain the recommended duct size in square inches.
Example: For instance, if the required airflow is 1200 CFM and the desired velocity is 400 feet per minute, the calculated recommended duct size will be displayed after clicking “Calculate.”
